Toner (Non-conductive Specimen) SEI

Chemistry, Plastics / Polymer

Toner is composed of particles approximately a few micrometers in size, and the surfaces of these particles are covered with fine particles such as pigments and additives. These fine particles are known to significantly affect the performance of the toner. Since toner is a non-conductive material, measures against charging, such as observing at low accelerating voltages or coating with conductive materials, are essential. Using FE-SEM (JSM-IT800) at low accelerating voltages, we were able to clearly observe the shapes of the toner particles, which measure in micrometers (µm). We also confirmed that fine particles are attached to the surface of the toner.
